to improveprice per multiple of the unit so that noniental ctl'ort isrequired to ascertain the price of the articles sold.

In accm'daluie with the present; invention the cash drawer is located.in the base of a suitable cabinet on one face of which are orificesthrough which may be exposed a cirmimi-zcribed portion'oit a band havingunit values displayed thereon, while along the margins of the orificesare indicated the prices of the larger or multiple unit and at anappropriate point in each band there is provided a space or columnindicating the character and number of units agreeable to the valuesdisplayed in other columns on the same band.

The cabinet may contain from one to any desired number of bands forascertaining the price per unit or number of units less than thepredetermined multiple unit or different kind of multiple units.

The invention will be best understood from a consideration of thefollowing detail description taken in connection with the accompanyingdrawings forming a part of this specification, in which drawings,

Figure l is an end elevation partially in section of a cabinet embodyingthe present invention. Fig. 2 is a front elevation of one of the displayorifices extending along the drawer side of the cabinet.

Referring to the drawings there is shown a casing 1 having its upperportion constructed to receive a drawer 2 which may be of the typeusually employed in connection with. cash receptacles, while forconvenience of observation the front of the cabinet may be in the formof an inclined partition 3 through which is formed anumber of spacedparallel narrow orifices 4c elongated in the direction of the length ofthe cabinet.

Located immediately behind each orifice 4, which latter may be closedwith a transparent covering 5 at the back, is a roller 6 v having ajournal 7 mounted in the sides of the cabinet: and at one end, or atbothends it so desired the roller 6 carries a gear wheel 8, while theournal or shaft 7 extends through one end of the casing and there'arries a crank 9 by means of which the roller may be readily rotated,in either direction.

Adjacent to the roller (3 is another roller 10 having a journal 11provided with bearings in the ends ot the casing and at one or both endsof this journal there is a gear wheel 12 meshing with the gear wheel 8on the roller (3. 7

At an appropriate point within the easing and more remote from theroller (3 than is the roller 10, is another roller 13 having a journalor shaft 1% mounted in the ends of the casing and this roller 13 hassecured. thereto or to its shaft 14 at one or both ends a gear wheel 15in mesh with the gear wheel 12 of the roller 10.

A band 16 extends from the roller 1.0 to the roller 13, bein; carriedaround the roller ('3 and. on this band are columns of figures indicatedat 17 in Fig. 2, the arrangement being such that these columns offigures are visible through the orifices 4, being brougl'it by theroller 6 close to the transparent plate 5.

The alls ot the orifices 1 may flare outwardly and these 'alls haveimprinted thereon or carrying strips having suit-able legends printedthereon, as indicated at 18, these legends indicating the prices permultiple of units decided upon, properly spaced to agree with thecolumns on the respective bands 16.

At some point, preferably an intermediate point in the hand there is acolumn indicat ing the unit and on the strip 18 in each orifice is atthis pointa designation of the character of the unit.

There may be as many sets of rollers each with a band 16, housed withinthe casing 1 as may be necessary or convenient and each set of rollersmay be independent of every other set, each set of rollers being underthe control of an individual crank 9.

In the specific example shown in the drawings, it is assumed that theprices are per lntlndredweight and that the units are pounds. Underthese circun'istances the unit column of the band will show from onepound to ninety-nine pounds or any other arrangement desired, while theprice per hundredweight will be given on the strip 18, this strip beinglong enough to indicate ni'unerous different prices per hundredweieht.There will be as many columns on the hand 16 longitudinal thereto asthere are prices per hnndredweight and in each column opposite or inline with'the unit in dication so as to match each and every one of thehuinlredweight prices will be num bers indicating the price per unit atthe hundredweight price.

lly nrmiding a suitable number of bands 1(% with carrying rollers andcorresponding orifices l the device may be made to indicate at a glance.prices per hundredweight, per ten, per bushel, per yard, or any otherdesignation desired.

Since the rollers 6, l0 and 13 are interconnected through the gearwheels 8, 12 and 15 any motion imparted to the roller (3 through itscranlt 9 will be transmitted to the rollers 10 and 13. but the saidrollers 10 and 13 will turn in opposite directions, one rolling the band16 thereon, while the other is unrolling it therefrom. If the band be insntliciently taut condition initially it will retain this condition atall times because of the uniformity of movement of the several rollers.

Suppose that some article sells for '75 cents per hundredweight and thatit be desirable to find the price of two pounds of the article at such aprice per hundredweight. The appropriate one of the cranks 9 is rotatedby the operator until the band controlled thereby has the articledesignation 2 brought into sight through the corresponding orifice l. Byglancing along the orifice until the hundredweight designation of T5cents seen it will be found that on the hand beneath the saiddesignation of 75 cents there will be displayed the designation of twocents which will be the price for two pounds at '75 cents per hundredpounds. ()ther amounts are found with equal ease and much mental effortis avoided especially in complex conditions, the example given beingmerely illustrative.

il hat is claimed is:

1. A computing device comprising drums positively connected for rotationin opposite directions, a flexible band wound upon and extending fromdrum to drum, a roller positively connected to the said drums forimparting rotative movement thereto, said roller being traversed by theband, and acasing having orifices each longitudinal to the roller, theband having designations thereon indicating units and prices, any oneunit or multiple thereof with the prices therefor being visible throughthe orifice.

An automatic computing device comprising a suitable cabinet havingorifices there-through each with a fixed price scale displayed on onewall thereof, and a means for displaying the prices of various units ofthe larger prices shown at the margins of the orifices, comprising aflexible band containing columns of prices and a column of units, aroller adjacent to the orifice and underlying the band, a drum receivingone end of the band, another drum receiving the other end of the band,and gearing connecting the roller and drums for simultaneous positiverotation.

33. A device of the character described comprising a suitable casing, amoney receptacle in the base thereof, said casing having on one face aseries of parallel orifices extending across said face and each providedwith price indications for large units, a flexible band for each orificemounted interior to the casing and containing in trans verse rows smallunit indications and prices per unit based on the larger unit prices, a

. roller within the casing adjacent to each orifice and traversed by theband, spaced drums for the respective ends of the band andinteconnecting gearings between. the roller and the band receivingdrums, the said band being operable from the exterior of the casing.

In testimony that I claim the foregoing as my own, I have heretoa'liixed my signature in the presence of two witnesses.
